The i.r. spectra of three cyanobicyclohexyls with three, four and seven carbon atoms in a linear side chain were investigated. Dichroic spectra of the compounds oriented between KBr plates were obtained for the crystalline, smeetic and nematic phases. Raman spectra of the crystalline and isotropic p
Superconductivity induced renormalization of Raman-and infrared-active optical phonons is studied for undoped and TΒ’-reduced Pr-and Zn-substituted double-chain YBa2CuaOa materials. The magnitude of the phonon frequency and the linewidth variation upon cooling below T, is found to be dependent on the
